Abstract

La présente invention concerne une structure et un dispositif terminal. La structure comprend une plaque de guidage de lumière, la plaque de guidage de lumière étant située entre une caméra orientée vers l'avant et un verre protecteur, et une projection de la plaque de guidage de lumière, dans une direction perpendiculaire à un écran d'affichage, recouvre une projection d'une encoche, dans la direction perpendiculaire à l'écran d'affichage. De plus, la structure comprend aussi une ou plusieurs sources de lumière colorée situées sur une face latérale de la plaque de guidage de lumière et utilisées pour émettre de la lumière d'une couleur spécifiée sur la face latérale de la plaque de guidage de lumière sous la commande d'un processeur. La plaque de guidage de lumière est en outre utilisée pour modifier une direction de propagation de la lumière de la couleur spécifiée dans la direction perpendiculaire à l'écran d'affichage, de telle sorte que la plaque de guidage de lumière affiche la couleur spécifiée. Avec la mise en correspondance de la plaque de guidage de lumière fournie avec les sources de lumière colorée fournies, des rayons de lumière émis à partir des sources de lumière colorée sont réfractés dans l'encoche couverte par la plaque de guidage de lumière et sont émis, de manière à ce que l'encoche soit couverte, ce qui permet d'améliorer l'effet d'affichage du dispositif terminal.
